    Too bad about reading Kuhn and not understanding him. Too bad about starting a polite discussion and ending it with insults.

    Thanks for the Weinberg reference, I will look that up. It would have been nice to let my know what you taught nonsense - maybe I would have learned something.

    What I was writing was a brief synopysis of current philosophies of science. If you found them tiring, that's just too bad.

    "As to whether we are talking experts, or laypeople, the question that comes to mind most quickly is, "who gets to choose who qualifies as an expert?" "

    This is an important question in the philosophy of science. The quick answer is that "the community of scientists". Of course we can expand this, but in general the community of scientists is a very tight group, which inducts its new members, chooses what's right and wrong etc. There are outside influences, of course. For example, if some funding body thinks nanotechnology is important, the community doing this kind of research will grow etc. The main thing to understand is that unlike what most people (including scientists) think, science is a SOCIAL phenomenon.

    "In any case, my issue has always been with the '95% certainty' aspect of this announcement."

    Given a normal distribution (of say, ages of the universe), there is a 95% probability that the actual value will lie within two standard deviations of the mean. This gives us both the stated spread of ages, and the 95% value.

    You must keep in mind that this is a statistical range and certainty. If the calculations that you make, your assumptions, formulae whatever are wrong, then you'll have a different mean value and range etc. So, what they are saying is, given these assumptions, these observations, these models, we are calculating such and such age for the universe. Within these restrictions, there is a 95% chance the actual age is within the range given. It is a best guess.

    "Regarding your mention of uncertainty (as in Heisenberg's example) this is, in fact, my point. If we can't measure multiple variables accurately, how can we account for the innumerable potential variables in measuring the age of the universe?"

    Heisenberg's principle puts a fundamental limit on observation (measurement). It simply cannot be circumvented (the act of measurement is the source of uncertainty). It's effects, however, tend to be constrained to the quantum level - usually electrons, atoms, molecules etc.

    Again, the question of error or uncertainty is not a question of only measurement. We can't account for all the variables in measuring anything. We make a best guess at a model, a best try at measuring the variables involved. We can get better estimates of the ages by either making better measurements, or coming up with better models. A better model may be more complex, to take into account more features of physical reality, or it may be based on variables that are easier for us to measure, etc.

    "Sure, standard deviation might allow for the age, given enough measurements, but what about the percentage of certainty - particularly if only one yardstick is being used? How can we pick a number like .95, or any other number?"

    So, what's happening is not "enough mesurements". There is an assumption of a particular distribution, and the .95 is the area this distrubution under two standard deviations away from the middle (mean). So, it's a purely statistical value. I believe if you go on std. dev. away from the mean, you get .68, etc.

    "In regard to the creationism vs. science camps, I am not saying that it is possible to hold both views."

    Yes. I think this would be impossible.

    "I am saying that one must always consider the possibility that one is wrong. Be prepared for the pardigm shift."

    I think this would also be impossible. Say I'm a creationist. I believe in devine revelation, that my holy book holds certain truths. It is unlikely that any evidence against these truths will convince me, because of the strength of my belief. When the two sides of the argument are so far apart in their validity claims, I don't think there is a very good chance of "changing sides".

    As for the paradigm shift. You really should consider reading Kuhn, because he's the guy who coined the term. In particular, you can't call creationism a paradigm, since it does not lead to new research or new discoveries. It is more properly a dogma - accepted at face value because of its divine origin.

    "Tangentially, I should mention that, while we are most familiar with extreme views on this subject, there are middle views. Many people, including scientists, believe in the "Intelligent Design" theory for example."

    Well, that's the great thing about being able to think, isn't it? You can take two ideas and see if you can work out a new synthesis. Unfortunately many people, scientists or not, simply believe a single point of view, without thinking too much about its merits, consequences etc.

    "Finally, on the subject of "Is the theory good enough to answer my questions", Kuhn writes that truth cannot be a criterion of scientific theories. Therefore all theories are equal."

    This definitely is not right. All theories are not equal. Some are much better than others is DOING CERTAIN THINGS. The value of a theory is definitely linked to what you want to do with it. It's just that you can't you can't say that this theory is good because it's true.

    "it simply means that your acceptance or rejection of the theory is predicated on what makes sense to you. It might not be what makes sense to me."

    This is absolutely right, and not limited to theories. This is how humans think. There are no universal truths. However, most communities come up with a consensus on what they believe is right, such as church doctrine, science textbooks, laws etc.

    Although I might agree with your final sentence, I don't think you are being fair. Scientific articles are written for the auidence of experts in their fields.

    He is saying, if you want to find the answers to your questions, there are many books written on these subjects, astronomy, error analysis etc. He's not being insulting, he's saying that these answers are out there, not hard to find nor too hard to understand.

    "From my perspective the argument is that what some would choose to see as theory, some are reporting as almost-fact."

    It's important, however, who sees what as a theory and who sees it as "fact". Are we talking experts, or laypeople? Is the idea new or established? I'll give you an example. Say you don't know anything about molecules or atoms. You put some sugar in some water. What happens? You mihgt theorize that the sugar has disappeared. What if you do know about molecules etc? I could perhaps persuade you that the sugar has dissolved. From then on, you would make factual statements about solids dissolving in solvents...

    "And we will be limited to theory for a long time, as in possibly forever."

    So what? It's a question of, "Is the theory good enough to answer my questions?". If not, how can it be made better? There are not claims about truth here, just explanation and prediction and understanding.

    "Both camps in this discussion should keep their minds firmly open."

    If you are referring to creationism vs. science camps, there is a big difference between these two. The first uses revelation as its source of validity, the other evidence. I don't think you should ask anyone to accept both claims - they are fundamentally different.

    "True, it's less comfortable, but unless you are responsible for the creation of the universe, you must be prepared to have someone else refute your set of beliefs."

    I don't think you can prove the existence of god, hence prove creationism. As for being prepared to have someone refute my theories, sure, that's how science works. (I recommed "The Sturcture of Scientific Revolutions", by Kuhn, if you are interested in this.) But like I said, you are not going to be able to come up with evidence to prove creationism, since the claim is based on revalation rather than physical/theoretical evidence. (Kuhn will tell you that these two sorts of claim are incommensurate - you gotta pick one or the other, but you can't mix.)

    "If I remember correctly, the original issue many had was with the very unspecific period that was cited, and the supposed accuracy that surrounded the claim. I'd have to say that it was simply irresponsible, and rather egotistical."

    Uncertainty is a fact of both experiments and the universe (Heisenberg's uncertainty principle). I don't think it's fair to call people irresponsible and egotistical for doing things that are impossible to avoid.

    You've never owned a vehicle - that's great. You still "deal" with car companies because all the stuff you buy in stores are shipped using trucks, vans etc. You still "deal" with oil companies because they provide energy for such vehicles, power plants etc. You seem to be unable to deal with a degree of abstraction.

    Getting back to my original point, which you never adressed. Americans love their cars. Their energy costs are incredibly low. This combination causes a huge amount of pollution. Recent trend towards the buying of SUVs etc. has led to lower efficiencies in gas consumption. This is why the construction of some public transport project will help reduce pollution.

From this you conclude that I think government can do no wrong. By what feat of reasoning did you accomplish this?

    You are right, I don't like big companies. Their sole motive is profit, and I think this is dangerous, since anything else becomes subservient to their goal of maximizing profits: environment, human rights, communities etc. To suggest that there would be no jobs without big companies is just dumb - unless you have some evidence to convince me otherwise.
